Designed to mitigate the often weak, noisy audio outputs of laptops and phones, the Sadie from Blue comprise a pair of sealed, over-ear headphones. They sport 50mm fiber-reinforced dynamic drivers to deliver a powerful sound and provide a frequency response of 15 Hz to 20 kHz; more importantly, the headphones are built around an on-board 240mW amplifier, which helps in improving the sound quality of the aforementioned devices. As such, the headphones provide a dynamic and precise sound, no matter the inherent quality of the sound source.

These headphones come with two detachable cables, one with iOS controls and a microphone for smartphone communication and Siri control, the other providing an audio connection to any device without the bells and whistles of mobile communication. Also included are a soft case and a 3.5mm to 1/4" adapter.
